[0009] Furthermore, the insertion slot is arranged longitudinally, and the insertion plate is arranged longitudinally.

[0010] Furthermore, the plug plate and the plug slot are interference-fitted.

[0011] Furthermore, the inner side of the wheel hub is provided with several reinforcing plates.

[0012] Furthermore, the surface of the fan blade is provided with fan blade reinforcing ribs.

[0013] Furthermore, the hub has a shaft hole at its center.

[0014] Furthermore, both the hub and the fan blades are made of plastic.

[0015] Compared to existing technologies, this utility model uses a fan blade that is snapped onto a hub. The end of the fan blade is provided with a connector plate, and the outer side of the hub is provided with a connector groove corresponding to the connector plate. The end of the connector plate is provided with a snap-fit ​​block, and the connector groove is provided with a snap-fit ​​hole corresponding to the snap-fit ​​block. This makes the connection between the fan blade and the hub simple and secure, the fan blade easy to disassemble and assemble, easy to clean, and easy to replace if a fan blade is damaged, avoiding affecting the use of the entire fan blade and providing a good user experience.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4This utility model discloses a fan blade mounting structure that facilitates easy assembly and disassembly. It includes a hub 1 and several fan blades 2 snapped onto the outside of the hub 1. Each fan blade 2 has a connecting plate 3 at its end. The outer side of the hub 1 has a corresponding connecting groove 4 for the connecting plate 3. Each connecting plate 3 has a snap-fit ​​block 5 at its end, and the connecting groove 4 has a snap-fit ​​hole 6 corresponding to the snap-fit ​​block 5.
